Question

What are example of ecological lichens?

Answer 1

Rhizocarpon, Rinsodina are first colonizers in xerosere.

Explanation:

Rhizocarpon, Rinsodina etc., are the colonizers in the xerosere. On the bare rocks spores are of these lichens (algae+fungi symbiotic association) partners are deposited from distant sources by wind, small ormanisms etc. These are the common species of crustose lichens, which colonize on the bare rocks. These begin the slow process of rock disintegra­tion. Particles of rocks and dead organic matter of lichens accumulate on the rocks surface. It provides conditions, suitable for the growth of higher forms of plants. Thank.
